8 0

Answer:

A

Explanation:

The correct answer would be that <u>the sperms are changing chemical energy to kinetic energy.</u>

<em>In order to power the movement of the sperm cells, chemicals in the form of glucose molecules are hydrolyzed and the resulting energy from the reaction is used to power the movement of the sperm cells.  Moving sperm cells possess kinetic energy. Thus, we can say that the chemical energy in the glucose molecules is converted to kinetic energy in the sperm cells.</em>

The correct option is A.

Evolution - It occurs due to the continuous variations and diversifications coming from the past generations

Natural Selection - In this process, the individuals are naturally selected by the environment that fits in perfectly!

Evolution - Driven by natural selection

Natural Selection- Driven by new characters that are the results of mutations

Evolution - Duration of Action Acquires millions of years

Natural Selection -  Can be done in a short duration

In order, duck's phases of ending a relationship are:
emmasim [6.3K]
Duck viewed relationships as a series of events. There are four main phases, in which the perception of the people involved in the relationship changes due to strain from different factors.  The phases are:

1) Intra-psychic phase
The individual does not express dissatisfaction or unhappiness with the relationship yet but feels it.

2) Dyadic phase
Discussion regarding the negative feelings is usually carried out in this phase, and anger and guilt tend to rise.

3) Social phase
The separation of the two individuals is shared socially and both choose their own friends and supports for this phase.

4) Grave-dressing phase
This phase occurs some time after the relationship has ended, and the individuals will look back thinking of all the things they did correctly, while also recollecting the negatives of the other person. Trust in relationships is rebuilt in this phase as the individual becomes ready for a new relationship.

Why don't all plants use the c4 or cam pathways to avoid photorespiration?
12345 [234]

<span>Not all plants use the C4 or CAM pathways to avoid photorespiration because they require a lot of extra energy to perform their function. In photosynthesis, minimizing water loss is essential; C4 plants relocate the carbon dioxide to lessen photorespiration while CAM plants indicates when to extract carbon dioxide. Their function is also related to plants survival where C4 plants is usually a summer plant while CAM plants is suited to thrive in desserts. Therefore, only plants that need special requirement to survival use these pathways.</span>
